Overall smoothness and connectedness in the game was very good. 120Hz monitors such as the BenQ are not only able refresh to frames of the game twice as quickly but are also able to update input responses from the mouse twice as often. This effect is greatest at a frame rate of 120fps but even at 60fps provides a significant advantage in this regard over even the most responsive 60Hz LCD monitors. Coupled with low input lag, which is covered in the next section, the game has a level of smoothness that no 60Hz LCD can touch.

That's a great site you've linked to. It looks really plain and a bit boring to look at, but the auther clearly knows his stuff when it comes to the critical technical aspects of monitors. I'm currently reading Matte Vs Glossy Monitors.

I'm sorry to ask for so much, but could you guys help me and tell me what should I check when I buy a new monitor? So far I only check for dead pixels on a white background and backlight bleeding on a dark background.

1 more question. In different reviews the reviewers use different means to achieve the right color temperature (6500K) and gamma (2.2), does it matter which one I follow? Or the end result is the same no matter which settings you tuned?

I would go with the TFT settings because they include the ICC profile and I use the same x-rite colorimeter on my televisions and get good results. TFT has been reviewing monitors for a very long time.
